8 oz bittersweet chocolate, chopped
1 ¼ cups all-purpose flour
½ cup unsweetened Dutch-process cocoa powder
2 tsp baking powder
¼ tsp salt
½ cup unsalted butter, softened
1 ½ cups light brown sugar
2 large eggs
1 tsp vanilla extract
1/3 cup whole milk
1 cup granulated sugar
1 cup powdered sugar
Preheat oven to 350°. Melt chocolate in a heatproof bowl set over a pan of simmering water, stirring. Set aside, and let cool. Sift together flour, cocoa powder, baking powder, and salt in a medium bowl; set aside. Mix butter and brown sugar on medium speed until pale and fluffy, 2 to 3 minutes. Mix in eggs and vanilla, and then melted chocolate. On low speed, mix in flour and milk, alternating in batches. Divide dough into 4 pieces, wrap in plastic and refrigerate until firm. Divide each piece into 16 (1 inch) balls. Roll in granulated sugar to coat, then in powdered sugar to coat. Bake on sheets lined with parchment paper for about 14 minutes, until surfaces crack. Let cool on wire racks.
